Description

Technical Field

[0001] The present invention relates to the technical field of papermaking, and more specifically, it relates to a dust removal device applicable to a paper rewinder. Background Art

[0002] A rewinder is a device used to rewind, organize, and process coils of materials such as paper and film into finished coils that meet the specified requirements. It realizes functions such as slitting, trimming, and rewinding of the coil by precisely controlling the winding tension, speed, and cutting accuracy, and is widely used in industries such as papermaking, printing, and plastic film. The rewinder can not only improve the material utilization rate but also ensure the quality and consistency of the finished coil, and is an important and indispensable device in modern coil processing.

[0003] During the process of rewinding paper, the rewinder will cut the paper through a cutter to cut the paper into the required size. However, a large amount of paper powder, paper fluff, and dust will be generated during cutting. These dusts will not only adhere to the surface of the coil, affecting the product quality, but may also scatter around the equipment, interfering with the normal operation of the equipment. In addition, dust accumulation may lead to equipment failures, reduce the service life, and even cause safety accidents such as fires or explosions. If dust removal is not carried out, it will also pose a hazard to the health of operators, such as causing respiratory diseases.

[0004] Most of the existing dust removal devices can only remove dust from the end face of the paper and cannot handle the paper fluff caused by cutting on the side of the paper, resulting in poor overall dust removal effect. Summary of the Invention
